MANHOLE INSIDE MONITORING SYSTEM

摘要

PURPOSE: A manhole inside monitoring system is provided to be advantageous for maintenance and repair by preventing damage to an antenna due to an external environmental factor of a manhole while monitoring the inside of a manhole without replacing a battery and remotely monitoring temperature, humidity and et cetera inside of a manhole installed in an environment in which many people come and go. CONSTITUTION: A manhole inside monitoring system includes a current sensor(12), a communication antenna(50), a monitoring module(20) and a communication terminal device. The current sensor converts an induced electromotive force of a power cable into current. The communication antenna is inserted and installed inside of a manhole lid and connects wireless communication to the outside of the manhole. The monitoring module is installed in a lower side of the manhole lid, stores power supplied from the current sensor, detects data including temperature and humidity inside of the manhole through the corresponding stored power and transmits the data to the outside of the manhole through the communication antenna. The communication terminal device is installed in the outside of the manhole and receives the data transmitted from the monitoring module.
